She does not have the qualifications needed to work with patients as a practitioner psychologist.
In the UK, anyone can call themselves a “psychologist.” However, titles like “clinical psychologist” and “forensic psychologist” are legally protected and require specific training and registration. These are referred to as practitioner psychologists.
Jessica has a PhD, which means she is a research psychologist. This does not qualify her to work clinically with patients. To become a clinical or forensic psychologist, you must complete a specialist doctorate, during which you need to show you can safely work with patients (as well as doing doctoral level research).
Jessica has only done the doctoral level research bit. She is charted because she registered with the British psychological society after doing her PhD. This doesn’t have any real benefit and anyone with a PhD in psychology (and any practitioner psychologists) can become chartered.
Anyone can call themselves a psychologist. However, clinical/forensic psychologist is a legally protected title. All practitioner psychologists working with patients need to be registered with the Health and Care Professions Council (HCPC). Research psychologists don’t.
Research psychologists are not regulated in the same way. This means they are not held to the same standards as clinicians.
It’s possible that this thread was started by her or her wife. Note how she refers to doing “forensic research” (technically legal) instead of referring to herself as a forensic psychologist (not legal). She has historically appeared on a Netflix show with the title of forensic psychologist. However, this is illegal and the show had to change it (despite Jessica reposting it to her socials).
She also claims she’s been reported to her regulatory body (which is false because she doesn’t have one).
